I'm surprised that, as a Samsung customer, it doesn't seem to bother him at all that his nearly-new device is completely unsupported.

Maybe it doesn't *need* extra support? As long as it works well, is relatively bug-free, and most Android apps continue to be version-independant, why would he care about it being supported? Not everyone needs (or wants) every single device they have to be constantly changing to be on the bleeding edge, after all.
